look before you buy !!

I can’t use this Torque Calc because the smallest stud size they have is 3/4” in diameter. It would be nice if they went down to 1/2” or so for your everyday mechanic.
Basically, it’s useless for me

nothing that great

Waste of my money that I paid. There are other apps for free that do more.

Great App

Very simple & easy to use! Easier than reading a chart on paper! Very happy about this.
